I've been connected to the internet via a dsl-router. There is another PC connected with the router and of course I can ping the ip address.The other PC works with Ubuntu 5.04 Hoary and there is a Canon S750 printer connected, which works fine with turbo print.

What should I do, if I want to use the printer also with DSL over my small network?

it is me once again. Now I have another PC in my network over the router - also with DSL on it. Still the same question, how can I use the printer on my ubuntu. Meanwhile the Ubuntu is on 7.10 and the printer is a Brother Laser HL-2030.

You don't say if the printer is connected to the dsl machines or to the ubuntu machine...

You can use the dsl cups extensions to share the printer connected to a dsl machine and you could also use cups on the ubuntu machine to share the printer with the dsl machines. I use the dsl cups extension to share a printer with other dsl machines and windows machines
